ABSTRACT Many of the performed researches all around the world aim to develop advanced technologies in order to enhance the performances of the in-frastructure systems, different from the actual ones, fact which involves multidisciplinary research (IT, sensoring, electronics, smart materials and others), aiming to assist engineers in realizing full benefits of struc-tural health monitoring. The paper presents a preliminary feasibility study of a system that can be used for damping of structural vibrations. Thus, shape memory alloys (SMA) components can affect through two mechanisms the structure's vibrations. The stresses from a SMA ele-ment that realize phase transformations, as a result of vibrations, have an effect on the frequency-amplitude characteristics. In addition, a dis-sipation of energy due to hysteresis in a SMA element can reduce the natural frequency and affect forced vibrations.
